HEADLIGHT-SUPPORT AND ADJUSTING MECHANISM THEREFOR.

SPECIFICATION formingpart of Letters Patent No. 731,938, dated June 23, 1903. Application filed February 7, 1903. Serial No. 142,395. (No model.)

To all whom it may concern;

Be it known that I, STRUBBE MoCoNNELL, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and Improved HeadlightSupport and Adjusting Mechanism Therefor, of which the following is a specification.

My invention seeks to provide a simple, inexpensive, and easily-manipulated means for supporting car-headlights and adjusting the same to deflect the light at any desired angle when passing around corners or on curves; and it comprehends generally a suitable base adapted to be secured to the engine-boiler or car-dash, a holder rotatably mounted uponthe said base having means for detachably securing the headlight thereto, and a peculiarly-constructed and cooperatively-arranged actuating means adapted to be set by the engineer or motorman.

In its more subordinate nature my invention embodies certain details of construction and combination of parts, all of which will hereinafter be fully explained, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a side elevation of so much of a locomotive-engine as is necessary to illustrate the application of rnyinvention thereon. Fig. 2 is a transverse section taken practically on the line 2 2 of Fig. 1. Fig. 3 is a longitudinal section of the means fordetachably securing the headlight to the holder and the cooperating parts. Fig. 4 isa detail View illustrating the several parts shown in Figs. 2 and 3 in detail. Fig. 5 is a view illustrating the application of myin vention to a streetcar. Fig. 6 is a horizontal section of the same, taken practically on the line 6 6 of Fig. 5. Fig. 7 is alongitudinal section taken on the line 7 7 of Fig. 5.

In the application of my invention for adjusting the headlights in locomotives a plate 1 is made fast to the under side of the headlight 2, and said plate has an integral pendent bolt 1 of the headlight 2, as clearly shown in Figs. 2 and 3, from which it will also be seen the bolt 1 extends down through a bearing-plate 3, which has a square aperture 3 to receive the square portion a of the bolt 1, whereby the bearing-plate 3 and the headlight 2 are caused to rotate with the plate 1, and to further hold the plates 3 and l in a tight engagement the said plates have studand-socket connections 5 and 6, as shown.

The bolt 1 has its round shank portion mounted within the apertured hub 7 of a supporting-plate 7, which extends lengthwise of the boiler-top, to which it is made fast by screws or bolts 7 that pass through foot portions 7 on the ends of the member,'as shown.

The supporting member 7 has an elevated or bridge portion, and the lower end of the bolt 1 projects below the said bridge portion, and the said projecting end is formed with a squared portion 1 to receive the inner end 8 of a horizontally-disposed and laterally-extending lever 8, it also having a threaded tap 1 to receive the clamping-nut 9, as shown.

The upper face of the member-7 has an annular seat or bearing portion 7", in which is formed a ball-race 7 to oppose the race 3 in the under side of the bearing-plate 3, and 10 designates bearing-balls held within the races 3 and 7 The outer end of the lever 8 is pivotally joined with a diagonally and rearwardly projecting link 11, which has means for adjustably securing it to a slide-rod 12, located on the outside of the boiler 13 and preferably at the rear of the usual hand-rail A, and the said rod 12 extends into the engine-cab O and pivotally joins with a lever 13, mounted within the cab, and which is provided with the usual rack 13 and spring-latch 13", as shown.

So far as described it will be readily apparent that by reason of the peculiar combination of the parts shown and described the engineer can by properly manipulating the lever 13 pull upon the rod 12 and impart a rotary motion to the headlight 2 in the direction and at the angle desired. Furthermore, by reason of the manner in which the several parts that are joined directly with the headlight are combined a simple, inexpensive, and positively-operating construction is provided.

The separate bearing-plate 3, connected to the bolt 1, as shown, admits of readily adjusting the bearing-balls, and the correlative arrangement of the bolt 1 with its attached plate, the connections between it and the said plate 3, and the supporting-plate 7is such that integrally therewith, such arrangement of parts being provided to admit of the ready removal of the headlight when desired Without disturbing the supporting and actuating means therefor.

The lever 8 in the modified arrangement is connected to a link-rod 15, which joins to the lower end of a lever 16, mounted upon the inside of the car-(lash, and which has a springlatch 17 for engaging the rack 18 in the ordinary manner.

From the foregoing, taken in connection with the accompanying drawings, it is believed the advantages and the manner in which my invention is manipulated and its operation will be readily understood.

Having thus described myinvention, what I claim, and desire tosecure by Letters Patent, is

1. In a mechanism of the class described, thecombination withabaseincludinga bridge portion, a centrally-apertured integral hub projecting upwardly from said bridge portion, said bridge portion having a ball-race in its upper face, surrounding said hub, a rotatable plate, having a centrally-apertured and a countersunk portion, mounted upon the upper face of said bridge portion, its countersunk portion cooperating With the bridge-hub, said plate having a ball-race opposingthe ball-race in the upper face of the bridge portion, a headlightdetachably connected to said plate, a bolt for cooperating with said plate to hold the parts together, said bolt having a round portion and a square portion near its lower end, and said bolt being disposed with its round portion in the hub-aperture and with its square portion projected below the under surface of the bridge portion, a lever secured to the square portion of the bolt and a nut on the end of the bolt for securing the said lever to said bolt, an actuating means comprising a second lever, a pawl-and-rack device therefor, a connecting-rod and an adjustable link member, the'latter being arranged to connect the rod with the lever secured to the bolt, for the purposes specified.

2. A mechanism for the purpose described; comprising a bracket, a member rotatably mounted on the bracket and adapted to be fixedly joined with a headlight, said member having a pendent bolt rotatably mounted in and projected below the bracket, a lever mounted upon and radially extended from the projected end of said bolt, and an actuating means, the latter comprising a lever, a paWl-and-rack device therefor, a connecting rod and an adjustable link member, the latter being arranged to connect the rod with the radially-extended lever on the turn-bolt, all being arranged substantially as shown and for the purposes described.

3. In a mechanism as described; the combination with a supporting-plate adapted to be fixedly held on the headlight-bottom and having a pendent bolt provided with a square and a round portion, and a base member having an apertured hub for receiving the round portion of the bolt and provided with a ballrace on its upper face surrounding its hub; of a plate rotatably mounted on the bracket and having a ball-race for opposing the ballrace in the upper face of the bracket, said plate having means for interlocking with the headlight-supporting member and provided with a central countersink portion for cooperating with the base-hub and a square opening to engage the square part of the bolt, said bolt being extended below the base-bracket, a lever secured to the projected end thereof and extended radially therefrom, a single clam p-nut for joining the several parts, the bearing-balls, and an actuating mechanism operable from the engine-cab for shifting the said radially-projected lever, for the purposes specified.
